Abstract
THE F-type of potato virus recently described by Clinch, Loughnane and Murphy1 and Murphy and Loughnane2 is evidently widely distributed. At Canberra in January 1936 a virus which was carried without symptoms in a number of solanaceous hosts was recovered from potatoes with a slight aucuba mottling of the foliage. The variety of potato was supplied under the name Arran Crest, but its characters were rather those of Arran Pilot. No tuber necrosis was noticed. The virus was recovered a number of times over a period of a year from the tubers of these plants, and from second generation plants grown from the tubers. The presence of the virus did not protect the potato plants from infection with Y-type viruses, and various other hosts containing it were infected with X virus and X + B without difficulty. It caused severe necrosis on pepper at mean temperatures below about 70° F.; above that, and at temperatures too low for the strong growth of pepper plants, the symptoms were milder. Solanum nigrum was found to be an important host on which the virus sometimes produced a very faint and transitory vein-clearing or mottle, but generally no symptoms at all. It could, however, be recovered from apparently unaffected plants in high concentration.
